Replying to Is there a flaw to my logic

I tried wikipedia because I'm sure someone has reasoned this out before but the relevant pages all look like gibberish to me.

So if there are a near infinite number of hypothetically possible realities given by a near infinite number of possible outcomes to a similarly infinite number of possible situations each the result of unique previous outcomes etc., then  the probability of each possible reality is equal irrespective of probability of the contributing outcomes.

So I can say that it's just as likely for me to have born in uganda to a pair of farmers as it would be for me to have been born to two space aliens on mars?

Or does that not make sense.
